COMBINED TYPE-WRITING AND COMPUTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 575,570, dated January 19, 1897.

Application filed April 22, 1896. Serial No. 588,538. (No model.)

To all whom it may concern.-

Be it known that I, HOLMES MAEsHALL, of Cleveland, Cuyahoga county, Ohio, have invented certain new and useful Improvements in a Combined Type-lVriter and Computing Machine; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to an improved combined type-writer and adding or computing machine; and itconsists, among other things, in the arrangement of the adding or computing machine below the type-writer and in view of the operator, a row of laterally-shiftable plungers ar 'anged over the keyboard of the computing-machine, and mechanism for each plunger for depressing said plunger and operatively connected with the required 0perating-key of the type-writer, so that the operation of said type-writer key will simultaneously effect the operation of the com putin gmachines key below said plunger.

My invention consists also in novel and meritorious features of construction and combinations of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a front side elevation of a combined typewriter and addingor computing machine embodying my invention. Fig. 2 is a left-hand side elevation of the same. Fig. 3 is a top plan in section on line 3 3, Figs. 1 and 2.

The type-writer A is suitably supported from legs 13, mounted upon the top C of a table or desk. There are four legs B, arranged in pairs, located at the left-hand side and right-hand side, respectively, of the machine.

The adding or computing machine D is mounted upon the table-top or desktop C bet-ween the two pairs of legs and sufficiently near the forward legs to enable the operator to see the com putin g-machin es sight-holes 6?, through which the amount. that is added and registered by said machine is exhibited. Said sight-holes are arranged in a row in the usual manner widthwise of the top of the forward end of the adding-machine. The addingmachine in the case illustrated is provided with eight rows of operatingkeys D, and said rows are arranged forwardly and rearwardly of the machine. The two right-hand rows of keys D are instrumental in registering cents or fractions of a dollar and the remaining six rows are instrumental in registering dollars. The third right-hand row of keys D is the units row, and thence to the left are the tens row, hundreds row, thousands row, tenthousands row, and hundred-thousands row in the order referred to.

A spiral spring D confined upon the stem of each key D, between the keys'head and the top of the case of the adding-machine, acts to retain said keyin its upper or normal position.

The construction and operation of adding, computing, or calculating machines are so well known by those skilled in the art that further reference thereto or a more extended description thereof is not considered necessary in this specification. Suffice it to state, therefore, that any approved construction of adding, calculating, or computing machine is employed, and that the amount registered or added is exhibited or visible through the sight-holes (Z of said machine; that keys D constitute the operating-keys of said machine; that the number and denomination represented by any one of said keys are registered upon the depression of said key; that there are nine keys in each row of keys, and that the keys of each row of keys, commencing with the forward key, are instrumental in registering numbers 1, 2, 3, 4, (5,77 (6,77 (47,77 (68, (07,7 of the denomination represented by said row of keys.

Two horizontal and parallel bars E E are arranged asuitable distance above and widthwise of the adding-machine, and are arranged a suitable distance apart between the rear end and forward end of said machine. Bars E E are suitably supported from upright arms or standards 6, rigidly secured to the case of the adding-machine. A carriage G extends between and is mounted upon and adapted to reciprocate endwise of bars E. Said carriage is of any suitable construction, and consists, preferably, of a frame terminating at its forward and rear ends in any suitable nu mber of sleeves or slides G, slidably mounted upon bars or slideways E.

A row of tilungers ll, arranged forwardly and rearwardly of the addingmachine and just above the latters keyboard, is provided, and said plungers are adapted to depress the different keys, respectively, of any one of the rows of keys of the adding-machine. Plungers ll are located directly below carriage G, and each of said plungers is provided with an upwardlyextending stem 7t, that has bean ing in an upright box 9 of carriage G, and a suitable distance above said carriage is provided with a head it. A spiral spring 7L2, confined upon the stem of each plunger between head 7t and the top of the plringer-carriage, acts to retain said plunger in its upper or normal position.

By the construction thus far described it will be observed that upon depressing any one of the plungers against the action of the spring acting to retain said plunger in its normal position when the series of plungers are in position over any one of the rows of operating-keys of the computing-1nachine the key in said row of keys that is below the plunger being depressed is depressed also, and thereby operated, and it will, furthermore, be observed that the plunger-carriage can be shifted laterally in the one direction or the other in order to bring the plungers in position over any one of the rows of keys of the adding-machine. I therefore provide mechanism whereby the Hunger-carriage is shifted from left to right or from right to left, according as the paper-carriage of the type-writer, to which I will presently refer, is shifted from right to left or from left to right, and I provide also mechanism for each of said plungers for depressing the plunger and opcratively connected with the key of the type-writer that bears and is instrun'iental in printing the numeral represented by the adding-machines keys adapted to be depressed by said plunger, and hence when it is desired to print a column of amounts upon the paper carried by the type-writers papercarriage the adding-n'iachine will, duringthe printing of said amounts upon the paper, add them and display the sum at its sightholcs, so that the operator is informed of and can at once print the sum upon his paper without delay.

A designates the operatingkeys of the typewriter. Said keys are operatively connected in any approved man nor with different vertically-tilting levers A operatively connected in the usual. manner with the type-bearing levers of the type-writer. Mechanisms for cstablishing operative connection between the typebearing levers of a type-writer and the type-writers operating-keys are so well understood by those skilled in the art that further reference thereto or description of same in this specification or illustration thereof is considered unnecessary. Suffice it to state that the vertically-tilting levers A that are instrumental, as already indicated, in operating the type-bearing levers of the typewriter, are fulcrunied at one end upon a hori- 7.01itally-arranged red A". (See Figs. 11. and 2.)

A series of bail-shaped vertically-t illiing levers K, arranged between the typewriter and adding-machine, have their central members engaging grooves or recesses 7i", formed in the top and extending transversely of the heads of the different plunger-stems, respectively That is, the head it of the stem 71 of each plunger ll upon its top has a transversely-arranged recess 7r engaged by the central member of a vertically-tilting lever K. levers K are arranged in a row forwardly and rearwardly and are fulcrumed at K at or near the forward extremities of their end members to forwardly and rearwardl y extending bars L, rigid with legs A. The foremost hail-sha md lever is the shortest, and each of the remaining bail-shaped levers is somewhat longer than the n ext forward lever and straddles and is fulcrumed a short distance rearward of the next forward lever, and the lever-supporting bars are suitably notched or cut to accommodate the aforesaid arrangement of the fulcrumed ends of the bail-shaped levers. Said levers, it is obvious, are instrumental in effecting the depression of the different plun gers, respectively, and are operatively connected, by means of links M, with the typewriters levers A adapted to be O [J0l't,tll(l(1 by the typc-writefs keys that are instrumental in printing numerals, and each of said typewriter keys is operativcly connected with the bail-shaped lever that is instn'umental in the operation of the computing-machines key that bears and is instrumental in registering the corresponding number of the denomination recorded by the key-row of which said last-mentioned key is a member. For in stance, plunger marked 1. in Figs. 2 and i is instrumental in effectingthe depression of the key bearing the numeral l in the different rows of keys of the adding-machine, and the bail-shaped lever that is adapted to ctfect the depression of said plunger is operatively connected, through the medium of a link M and a lever A, with the typeovriter key A, that bears numeral 1.

Any suitable number of suitably-applied springs act to retain the bail-shaped levers in their elevated or normal position. A series of springs O are provided, preferably, atone side, or both sides, of the machine and are suitably attached at their lower ends to the different levers, respectively, and are suitably secured at their upper ends to a rod or rods 1', extending between and secured to legs A of the machine, as shown in lfi-ig.

Two rods Q and R (see Fig. 1) are rightly secured to and extend laterally of the central portion of the plungercarriage in opposite directions, respectively. ftod Q, at its outer end is operatively connected with the longer arm of: a vertically and laterally tilting lever S, that is 'fnlcrunied at S, preferably a short distance from itsupper end, to a stationary bracket a, rigid with the stationary frame of IOU ITO

the typewriter. Rod R is operatively connected at its outer end with the longer arm of a vertically and laterally tilting lever T, fulcrumed a short distance from its upper end at T to a bracket a, rigid with the stationary frame of the type-writer. Levers S and T are fulcrumed in the same horizontal plane and at their upper ends are operatively connected with opposite ends, respectively, of a horizontally-arranged rod U.

Rod U extends along the forward side and longitudinally of the suitably-actuated papercarriage A of the type-writer and is provided at any suitable point between its ends with an upright arm U, whose right-hand side is adapted to be engaged by the forwardly-projecting dog or arm XV, mounted upon the round rod or bar W, that extends longitudinally of the forward side and is a member of the aforesaid paper-carriage. Member WV is preferably adj ustabl y secured upon rod or bar XV by means of a set-screw V Arm U of rod U is preferably located about centrally between the ends of the rod, and the aforesaid dog or arm of the paper-carriage is located, preferably, near the right-hand end of the carriage, so that the type-writer, during the movement of said carriage between its point of starting at the right-hand end of the machine and the point at which its aforesaid dog or arm comes into engagement with arm U of rod U, can be operatedindependently of the adding-machine, and hence the operator can write upon the left-hand side of his paper any remarks concerning the items of the column of figures to be placed upon the righthand side of his paper, or any other matter that he desires to have appear upon the paper in addition to the numerical items; but as soon as the aforesaid paper-carriage, during the latters longitudinal movement, comes into engagement with the right-hand side of the upright arm or rod U the latter will be shifted longitudinally to the left and actuate lever S in the direction required to move plungercarriage G and the latters plungers to the right, and the arrangement of parts is prefably such that when said forwardly-projecting dog or arm of the paper-carriage first comes into engagement with arm U of rod U the plunger-carriage shall be in position (not shown) over the first row of keys at the lefthand side of the keyboard of the adding-machine, and shall thence be moved to the right from one row of keys D to the next row of keys D sim ultaneously with the leftward movement of the type-writer carriage. Then the typc-writers paper-carriage during its operation has arrived in its extreme lefthand position and is thereupon moved to the right into its starting position, rod U is also actuated longitudinally to the right by hand or in any approved manner and thereby actuates lever T in the direction required to move the plunger-carriage to its starting position at the left-hand end of the keyboard of the adding-machine.

I would also remark that the forwardly-proj ectin g dog or arm of the type-writer carriage can be oscillated rearwardly out of line with arm U of rod U, as shown in dotted lines, Fig. 2, and the plunger-carriage actuated into a position over the space had at the left-hand side of the keyboard of the adding-machine (shown in dotted lines, Fig. 1) when it is desired to operate the type-writerindependently of the adding-machine.

The recesses in the upper ends of the heads of the stems of the plungers accommodate the movement of the plunger-carriage without interfering with the operative connection between said plungers and the bail-shaped levers engaging said recesses.

My improved machine will be found especially useful in banks, clearing-houses, and wherever addition or computation and typewriting are to be done upon the same piece of paper.
